Abstract

A cutting element (20) includes a layer (23) of integrally bonded superabrasive particles disposed over a substrate (24). The layer has an outer circumference comprising at least one trough (22) having a distinct cutting point on either side of the trough. A rock drilling drag bit incorporating the cutting element and a method of cutting a material using the cutting element are also disclosed.

Claims

AMENDED CLAIMS received by the International Bureau on 02 May 2006 (02.05.06)What is claimed is:
1. A cutting element comprising: a layer of integrally bonded superabrasive particles, wherein the layer has a substantially planar surface and an outer circumference comprising at least one trough, the trough comprising a distinct cutting point on either side; and a substrate, wherein the layer is disposed over the substrate.
2. The cutting element of claim 1, wherein the superabrasive particles comprise diamond or cubic boron nitride.
3. The cutting element of claim 1, wherein the substrate comprises a metal carbide.
4. The cutting element of claim 1, wherein the substrate comprises a Group IVB, Group VB, or Group VIB metal carbide.
5. The cutting element of claim 1 , wherein the substrate is substantially cylindrical in shape, the substrate having an outer circumference, wherein at least one trough is formed into the outer circumference of the substrate,
6. The cutting element of claim 1 , wherein the layer has two or more troughs, the two or more troughs comprising a tooth having a distinct cutting edge between the troughs.
7. The cutting element of claim 6, wherein the cutter comprises a plurality of teeth.
8. The cutting element of claim 1, wherein the cutting element is incorporated into a drag bit for use in cutting material.
9. A rock drilling drag bit comprising: a cutting element having a layer of integrally bonded superabrasive particles, wherein the layer has a substantially planar surface and an outer circumference comprising at least one trough, the trough comprising a distinct cutting point on either side; and a substrate, wherein the layer is disposed over the substrate.
10. The rock drilling drag bit of claim 10, wherein the superabrasive particles comprise diamond or cubic boron nitride.
11. The rock drilling drag bit of claim 10, wherein the substrate comprises a metal carbide.
12. The rock drilling drag bit of claim 10, wherein the substrate is substantially cylindrical in shape, the substrate having an outer circumference, wherein at least one trough is formed into the outer circumference of the substrate.
13. The rock drilling drag bit of claim 10, wherein the layer has two or more troughs, the two or more troughs comprising a tooth having a distinct cutting edge between the troughs,
14. The rock drilling drag bit of claim 10, wherein the cutter comprises a plurality of teeth.
15. A method of cutting a material comprising: providing a cutting element comprising a layer of integrally bonded superabrasive particles disposed over a substrate, wherein the layer has a substantially planar surface and an outer circumference comprising at least one trough, the trough comprising a distinct cutting point on either side; initially contacting a cutting element to a surface of the material; and dragging the cutting element along the surface of the material to perform cutting.
16. The method of claim 16, wherein the cutting element contacts the material at a center of the trough, wherein the initial contact between the cutting element and the material occurs at two points on either side of the trough.
17. The method of claim 16, wherein the cutting element comprises two or more troughs, the two or more troughs comprising a tooth having a distinct cutting edge between the troughs, wherein the cutting element contacts the material at the center of a tooth.
18. The method of claim 16, wherein:
the cutting element has a plurality of cutting points; the cutting element initially contacts the material with a first one or more of the cutting points; and additional cutting points contact the material after the first cutting points have undergone abrasive wear.
19. A cutting element comprising: a layer of integrally bonded superabrasive particles, the layer having a substantially planar surface and an outer circumference comprising at least one trough, the trough comprising a distinct cutting point on either side and comprising a non-zero angle relative to a central axis of the cutting element; and a substrate, wherein the layer is disposed over the substrate.
